yellow spots or with black spots with yellow borders. The autumn form of fortunate,- f. autumnalis Bgff. (S») autumnal;, 
that flies in September and October only differs from the summer form by its much smaller me. A cotype 
from the collection of Boegeff is illustrated. - The Tar. alpiummrcans Vrty. from the Cottrc Alps, OuK, Val 
Susa in August is more similar to nicam, the enlarged spots of the forewings are sometimes widely con- 
fluent — In the Litoral of the Maritime Alps and the estuary of the Rhone the more brightly vermnion 
red subsp. nicaea Stgr. (Vol. 2, p. 29, plate 8 d and 8 c) ( faustina ) is found. - The var junceae Oberth. i \ ol. 
p 29) from the Pyrenees (Vernet les Bains) is brightly vermilion red mixed with carmine and smaller 
than the former. — We find var. oranoides (Bgff. i. 1.) Sag. ( = oranoides Bgff.) (2 m) m Catalonia (Manso o,< 
Vincens, Villa Major). The forewing spots in this race are more isolated, the bow-shaped spot b is larely 
conjoined on top and below with No. 5, mostly free on the upperside and quite separate in a number of specimens, 
so that the spots are situate as in orana. The colour is carmine-rose (not vermilion). The insects described were 
caught in September. The $ illustrated is from Llinas (September). From Limas (Catalonia) I received from 
Qiterci specimens of this fausta race taken from 3rd June to 19th July and then again in September. According 
to the particulars supplied by Querci fausta occurred in the cataloman plains thrice in the yeai 
(May/June, mid July and September) whilst in all other localities it only occurred m Aug./Sept. bASA... 
denominates the May/June form with forma macraria, the smaller July form with forma microsaria, both 
these forms scarcely differ one from another with the exception of minute differences m size. Dwarf specimens 
are called ab. lilliputana Sag. Further we have: ab. fractimacula Sag. m which the upper paid of spot of dvpua^>■ ■ 
forewings is absent and ab. sagarrai n. nov. ( = disjuncta Sag., praeocc.) with completely separate spots.l and . cu ?«. 
of fore wings. 
The subsp. preciosa Reiss. (2 m) from the Sierras around Albarracin (as type race) have more acute 
forewings. The red is brilliant. The enlarged and generally strongly confluent forewing spots are generally 
faintly surrounded as a whole with pale yellow. Sometimes this border is partly or entirely absent. Spots • > 
and 4 are always confluent along their whole width. The red abdominal tip is clearly present m the <J. I have 
similar although slightly varying specimens from Villacabras and Cuenca which I do not consider it necessary 
to name The type is illustrated. — faustina 0. from Portugal and Andalusia (Vol. 2, p. 29) is also considered 
a subspecies. I do not know the insect but according to the description it has nothing to do with preciosa. 
The cocoons of fausta are affixed on the food plant (Coronilla minima Jacq. and montana Scop.) just 
over the ground so that they are rather difficult to find. 
Z. baetica Rmb. (= faustina Dup.) (Vol. 2, p. 29, plate 8 b) from southern and western Andalusia, baetica. 
Grenada. It has a simple abdominal belt, a red collar is indicated. Ram bur captured it in April and again m 
September. — The subsp. murciensis Reiss (2 m, n), the type race from Totana and Sierra Espunna (Murcia) murciensis< 
differs from baetica by its slightly less brilliant yellow-red, the pronounced red collar, the very wide red abdonnna 
belt and indicated yellow streaks on the thorax, as well as the partial occurrence of a red tip to the 
abdomen in the The hind wings besides are more narrowly margined with black. The illlustrated specimens 
are the types. 
Z. algira Dup. (= algira H.-Schdff.) in Vol. 2, p. 29, plate 8 a. Contrary to the opinion of Oberthur. algira . 
who rejects algira Dup. because Duponciiel’s illustration does not correspond with lus description, I should 
like to subscribe to Lord Rothschild’s opinion and retain algira Dup.] bachaga Oberih. is considered as 
synonymous. — We have var. exigua Seitz. (Vol. 2, p. 29, plate 8 a) from the lower reaches of the Auies 
Mountains. Z. algira occurs on the coast in February and March and then again m June m a considerably 
smaller form. It is improbable however that this summer form represents a 2nd generation, m appearance it 
corresponds with exigua Seitz from the Atlas, which also flies in June. 
The larvae feed on Coronilla juncea L. and minima Jacq. The usual black dorsal spots are considerably 
increased so that they cover the whole back in a regular black pattern. The lateral stripes over the stigmata 
consist of a row of separate black markings. Above them the rosy-red ground colour forms longitudinal 
stripes, the upper part of which is intersected on each segment by the vertical sulphur-yellow spots. The belly 
is blackish; the hairs are short and fine. The caterpillar therefore is plainly provided with “poison” colouration. 
It rests openly on the food plant in the sun. The cocoons are longish barrel-shaped, white porcelain colour and 
glassy and resemble exactly those of Z. fausta. Contrary however to fausta the pupation occm s fairly high up 
on the twigs of the food plant. 
Z. marcouna Oberth. (Vol. 2, p. 29, plate 8 b) from Algeria (Marcouna, Constantine, Laghouat) is a very marcouna. 
rare insect. They are more thinly scaled than shown in the illustration, more rose coloured and partially have 
a border of white spots. 
Z. excelsa Rothscli. (2 n) from West Algeria (Djebel-Mekter near Ain-Sefra, 1600—1900 m) is larger excelsa, 
than marcouna , with wider wings and more densely scaled with brilliant red; on the underside the spots, aic
